differences between a573 grade 70 and a588 grade K steel, carbon steel plate is a kind of steel plate, and it is the abbreviation of common carbon structural steel. The carbon steel plate belongs to a large category of steel, including Q235, SS400, A36, SM400, ST37-2, etc. Due to the different names in various countries, the carbon steel standards implemented are also different. The ordinary carbon structural steel, differences between a573 grade 70 and a588 grade K steel is mainly used for construction machinery, mining machinery, heavy vehicles, bridges, pressure vessel plate and other engineering structures.
Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as differences between a573 grade 70 and a588 grade K steel, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.
Titanium microalloying is an element of differences between a573 grade 70 and a588 grade K steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in differences between a573 grade 70 and a588 grade K steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
